WILLIAM J. GAGNON, OF BRIDGEPORT, CONNECTICUT, .A.SSIGNOB TO THE BRANT ELECTRIC COMIAN'S, NECTICUT.

O15 BRIDGrEPORT, CONNECTICUT, CORPORATION 03 CON- CHAINPENDANT.

T0 aZZ w7zom z't may concem:

Be it known that I, WILLIAM J. GAGNON, a eitizen of the United States of America, residing in the city of Bridgeport, county of Fairfield, and State of Conneotient, have invented certain neW and useful Improvemonts in Chain-Pendants, of which the following is a specification.

The invention relates to chain pendants, and particularly to the pendant for chane et the type eonnnonly used for operating electric pull switehes.

A particular object of my invention is to provide a pendant which, alter installation is readily adjusted to a diferent length of ehain.

In the accompanying drawings, Figure 1 is a side elevation of an electric pull switch on the chain of Which my improved pendant is shown in side elevation; Fig. 2 is a vertical section through the pendant; Fig. 3 is an inverted plan thereof; Fig. 4 is a side elevation showing the pendant during the adjustment thereof on the chain; Fig. 5 is a side elevation of a lengthened chain to which my pendant is attached.

In the partieular form here shown, my improved pendant comprises a spherical body eomprising upper and lower hemispheres 10 and 11 respectively and an inter posed diaphragm 12 (Fig. 2), for giving added rigidity to the construction. The upper hemisphere is centrally apertured at 18 t0 a diameter slightly greater than that of the balls 14 of the chain on Which the pendant is designed for adjustment. The lower hemisphere 11 is centrally perforated t0 a diameter s0mewhat less than the diameter of the balls 14: and is radially slit at 16 to form a plurality et spring fingers 17. The peripheral edge of the hemisphere 11 is slightly outturned at 18 to form an engaging shoulder beneath which the outturned edge 19 of the hemisphere 10 may be spun to hold the two parts together. To strengthen the pendant, the diaphragm 12 is arranged between the adjacent edges of the two hemispheres and is held in place by Specification of Letters Patent.

the spun over edge 19. This diaphragm is eentrally apertured at 20 to permit the halls 14 to pass ireely therethrough.

T0 position the pendant on the chain, it is only necessary to pass the terminal hall 14 0:1 tl1e ohain freely through the apertures 18 and 20 of the hemisphere 10 and diaphragn1 12 respectively, and then force it throngh the aperture 15 of the hemisphere 11, tl1e spring fingers 17 of the latter spreading slightly (Fig. 4-) as the ball passes through. As soon the ball 14 ha passed throngh the aperture 15, the spring fingors retraet to their normal position, and inasmuoh as the aperture 15 is of less diameter than the ball14, a clownward pull npon the pendant serr'es 1nerely to press this hall against the enter faces et the ends of the spring fingers 17, thus forcing them the more closely together and constrieting the aperture 15 so that there is no possibility of the ball escaping through the pendant.

If it desired to shorten the ehain, the pendant is merely forced up 0Ver successive halls on the chain nntil it has reaehed the desired position, whereupon the chain 0X- tending beyond the ball may be ont off. On the contrary, when the chain is to be lengthened, tlze terminal ball 14 may be ont off, and the pendant adjusted upon the end of the added length Of chain, the other end of which is attached to the original piece by a coupling attachment 21 of any suitable con struction.

I claim as my invention 1. A chain pendant eomprising a hollow body having apertures in vertical alinement, the upper aperture oeing 0f greater diameter than the lower, and the body of the pendant surrounding the lower aperture being slotted t0 i:'or1n spring fingers. substantially as and for the purpose described.

2. A ehain pendant comprising; a hollow spherical body having upper and lower hemispheres with interengaged edges and a transverse diaphragm seated between said edges and serving as a stifiener, said members being apertured in vertical registm, the

apertures in the daphmgm and upper hemname t0 ths specification, in the presence isphere exceeding in diameter the aperture 0f tWO subscribng witnesses. in the lower hemsphere, said lower hemisphere being slotted around the aperture WILLIAM GAGNON therein to form a series of sprng fingers, substantiafly as described.

In testimony whereof I have signed my Wtnesses:
